[Value of endomyocardial biopsy in congestive heart failure in diabetics without coronary disease]. / Intérêt de la biopsie endomyocardique dans l'insuffisance cardiaque congestive du diabétique non coronarien.

Two cases of congestive heart failure in diabetic females are reported. One patient had moderate hypertension. Echography and angiography revealed a low-output dilated cardiopathy and ruled out the possibility of coronary artery stenosis and thin amyloid deposits were found in one patient. The evolution was favorable with a low-salt diet, associated with diuretic and vasodilator treatments. These case reports confirm the existence of a diabetic myocardiopathy, which may lead to congestive heart failure. They justify a complete hemodynamic analysis and a histopathological evaluation of the myocardium when this complication occurs.
